Subject: [TechAssist] RCA PTK171ABB turn on problem
> Greetings all
> We have an RCA PS52680 projo PTK171ABB chassis that needs multiple
pushes of the power button. Each time I hear the HV come up higher and
higher until it runs. All standby voltages OK. ESRed many caps (if not all)
in the power supply and horiz. circuits but still acts like a slow charging
cap. Once on, set runs and regulates fine. Any ideas appreciated as we now
have 2 of these monsters in the shop. Thanks.
